How to Convert Electronvolts to Watt-seconds

To convert an electronvolt measurement to a watt-second measurement, multiply the energy by the conversion ratio. One electronvolt is equal to 1.6022E-19 watt-seconds, so use this simple formula to convert:

watt-seconds = electronvolts × 1.6022E-19

The energy in watt-seconds is equal to the electronvolts multiplied by 1.6022E-19.

For example, here's how to convert 5 electronvolts to watt-seconds using the formula above.
5 eV = (5 × 1.6022E-19) = 8.0109E-19 Ws

Electronvolts and watt-seconds are both units used to measure energy. Keep reading to learn more about each unit of measure.


The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as eV, for example 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.


The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds can be abbreviated as Ws, for example 1 watt-second can be written as 1 Ws.
